LINE-SPACINGIQEVICEM To all whom itmag concern: n p Be it known that I, FREDERICK E. ROMIE, a citizen of;the United States, residingin the city of Oakland, in the county of Ala meda and State of California, have invented a new and useful Improvement in Line Spacing Devices, of'which the following is a specification. U My invention relatesto improvements in line spacing devices wherein a series ofregularly spaced and alined apertures operate in conjunction with a base t0;dlVid6 a -given dimension into a number of. equal spaces when a pencil is placed in successive apertures and the device moved or reciprocated parallel to said base. v r

'The primary object of the present inve'n: tion is to provide a newand improved and simplified device for spacing lines at equal distances as in cross sectioning drawings or dividing any one of a number of given dimensions into equal spaces, or the sainei dinumber of spaces readily visible to the eye. I a

It is also an object of the present inven tion to provide, an improved device-of the character described having meansfor indicating the number of equal spaces into which a given dimension may be divided 'for'c'ertain positions of the device. 4 I

A further object of theinvention isto provide aseries of alined and regularly or specially spaced apertures whoseposition :may be altered relatively to-a base of the-device, and also having means for indicating the number of spaces into which a given dimen-v I accomplish these and other objects a means of the device disclosed in the drawx the said specification and ings forming a part of the-present specifications wherein like characters of reference are used to designate similarparts throughout drawings,' and in which- Figure 1 is va plan view disclosing the de-' I closedat the lower left hand-corner of Fig.

Referring to the drawingsthenumeralil s-usedto designate a-plate, of any suitable shape or contour, having a base Qand a circular aperture 3 whose periphery is pro' I vided wlth an annular groove 4 and a slot '6 extendingfrom said periphery, the purpose of which Willhereinafter be more fully" set forth." n f The plate 1' is also provided with a series of alined and regularly spaced apertures 7 arranged on a curve substantially tangent to the base2'0f the plate 1 whereby a series of lines maybe drawn to produce gradually increasing or decreasing spaces by'placing apencrlpomt in successive apertures 7' and reciprocating the plate 1 along its base 2, said base2being arranged to be moved; along I a straight-edge, Trsquarefor the like not 1 shown. i i

Rotatably mounted within the circular aperture? of the -.p late l is'amember 8211'- ranged f-fiush with both sides ofthe plate 1 and provided with an annular flange 9 whose width and thickness isslightly lessthan the wlijcith and ldepth of thegroove 4.- in the pa e1. j fllh'eplate 1 ,is; preferably constructed- 0f celluloid or some other suitable transparent material having resiliency and elasticity whereby the flange 9ofthe member 8-will be frictlonally engaged by the sides of the annular groove at. to normally-prevent a free rotationjof said rotatable member 8, the pur pose of which w lljhereinafter be more f lly set forth...- r ..V

With a slot-l1 extending inwardlyfrom the H with a second 'line'of specially spacedapertures 14 arranged; for producing a seriesof speciallyspacedllnes for letterlng, a dis- 1 of the drawings;

1 The member 8 has a graduated protractorjadjacent one portionof the periphery there-o of, saidsgraduations'bein arranged-to register with an indicator, po1nt'16 on the plate J land at right'angles to theibase 2 thereof.

., The plate 1 is also provided with a semicircular top portion having agraduated pro- 1 tractor 17thereonf0r convenience of drafts- .",:,."l w --The rotatable member .8 is also provided 7 from the circular aperture 3, therein, said.

graduations 18 being arranged to indicate the number of spaces into which an inch may be divided by placing a pencil successively 'in the apertures 12 and reciprocating the plate along the base 2 when said apertures 12 'arealined with said graduations. For instance when the apertures 12 are alined With the graduation numbered 9 as indicated in dotted lines in Fig. 1 of the drawings, a line one inch in length and arranged at right angles to the base 2 of the plate 1, will be divided into 9 equal spaces when lines are drawn by a pencil point applied in successive apertures 12. r Y

The apertures 14, specially spaced, will similarly produce lines for lettering having two unequal spaces but ofthe desired width for the height of short and tall, or small and capital letters.

These special spaces for {lettering and other similarpurposes may also be altered by rotation of the member 8 to alter the angle of said alined and specially spacedapertures 14 relatively to the base 2 of the plate 1. p

To indicate the width of these specially spaced spaces for various heights of letters I have provided specially spacedindicators or graduations 21 upon the plate 1 with which the specially spaced apertures 14 may be alined to produce the required spaces or lines, in the manner hereinbefore described. I I I The rotatable member 8 is normally held againstrotation by the frictional engagement of the sidesof theannular' groove 4 against .the annular flange 90f the member 8 so that in operation the pencil point, not shown, may be inserted-in successive apertures and the device moved by means of said pencil point while drawing the lines, with out rotating the member 8 and-thus destroying the spacing being produced by themovement of the plate 1 and rotatable member 8 therein while traversing the paper.

The member 8'n1ay be readily removed from and placed within the aperture 3 by moving the slot 11 of the member 8 into register with the slot 6 of the plate 1, as disclosed in dotted lines in Fig. 4 of the drawings. While in this position opposite sides of the alined slots 6 and 11 are sprung into parallel planes when a further rotation of the member 8 will move the flange 9 on one side of the slot ll beyond and parallel with theadj acent surface of the plate 1 and a complete rotation will remove the flange 9 lines of almost any angle to the base 2 by alining the apertures 12 with the required graduation on the protractor 17 and placing oints through the apertures on both ends of the line. Byremoving the plate 1 from the paper a line may be readily; drawn between the two points. I

Having thus described my invention what I claim as new and desire'to secure by Letters Patent is I I I 1. A line spacing device comprising a plate having a straight-edge base and a cir cular aperture therein" and an annular groove in the periphery of said aperture; a member rotatably mounted within the aperture an'dhaving an annular flange of less width I and slightly greater thickness than the groove whereby the sides of said groove will tend to exert a pressure upon said flange I to normally prevent a free rotation thereof,

said rotatable member being likewise pro vided with aplurality of rows of regularly spaced and alined apertures which maybe arranged at anangle to said base whereby apencil placed in successive apertures will divide a given dimension into equal spaces 7 when said plate is movedalong sald base.
